What happen if I take the TB two time the same week?

Taking the tuberculosis (TB) test, typically the tuberculin skin test (TST) or the interferon-gamma release assay (IGRA), twice in one week is generally not necessary and can lead to confusion in interpreting results. If you receive both tests, the second test might not provide additional useful information, and the skin reaction from the first test may affect the second test's result. It's best to consult with a healthcare provider for guidance on the appropriate timing and necessity of repeat testing.
